6.2.5 Setting an Output Line for Invert
You can set the output lines to not invert or to invert.
For the GPIO Line
If the GPIO line is not set to invert:
 A low output signal from the camera results in a non-conducting Q1 transistor in the output
circuit (see Figure 18).
 A high output signal from the camera results in a conducting Q1 transistor in the output circuit.
If the GPIO line is set to invert:
 A low output signal from the camera results in a conducting Q1 transistor in the output circuit.
 A high output signal from the camera results in a non-conducting Q1 transistor in the output
circuit.
For the CL Spare Line
If the CL Spare line is not set to invert:
 When the source camera signal assigned to the line is high, the CL Spare line will transmit a 1.
And when the source signal is low, the CL Spare line will transmit a 0.
If the CL Spare line is set to invert:
 When the source camera signal assigned to the line is high, the CL Spare line will transmit a 0.
And when the source signal is low, the CL Spare line will transmit a 1.
